Help!
I'm 40, 41 this year.
I'm currently single, no kids, came out of a serious long-term relationship a year or so ago. All very amicable, we're still great mates etc. etc.
I am depressed. I'm on anti depressants (40 mg citalopram). I've been on and off ADs since my early 20s, when I was diagnosed with clinical depression. (History of an aunt and cousin who were both diagnosed with depression and committed suicide, although I can barely remember them).
The problem is that I don't know what I'm doing! I'm pretty sure I don't want kids. I have an awful and painful history with my older sister - who abused and bullied me all my life, and continued to do so until I finally cut contact with her early this year.
More and more I'm content to mooch around. When I take the dog out each day - anyone who meets me would never believe the brain mush I'm currently in. I'm happy, chatty, full of cheer...always remember who's doing what, how's this that and the other lol
But I'll never progress to make more important friends. I have friends though - but they don't live where I live, and these were friendships I forged years ago when I knew how
Both last weekend and this weekend I have used work as an excuse to not do something social - (invite from local friends (not v close but lovely) to a party and this weekend a night out with 2 people I'm quite friendly with)
what the hell is wrong with me? I'm on a pretty high (for me) AD dose so I'm not sure where I can go from here. I've had various different counselling over the years but nothing has really got to the crux of the problem.
I guess I'm just lost :( My dad (in a spirit of kindness) told me to 'live a little' when I last saw him and I tactfully hid myself away and had a cry.
Thing is I'm quite happy until someone (like my dad) says something (like the above) and then I feel mortified - like I'm the subject of sympathetic and pitying talk, and the one thing I can't bear is being thought of the subject of gossip.
I am social in my own strange way but on my terms. I don't like people to turn up unannounced - I loathe unexpected phone calls - but I like nothing better than to catch up with a friend on a weekend if we've scheduled a meet-up.
I'm also gainfully (self-) employed and make a good living in a job I had to go back and do university study and extra qualifications to do.
I'm not really sure what I'm asking? What am I doing wrong?
I look in the mirror and see an old person - and think of all the things my peers and friends have at the same point in life - and wonder what the hell will I do?
I also wonder if I'll ever meet someone who will consider me truly as a partner? Would you consider someone of my age who has never had kids (obviously I wouldn't spill out the guts of this post to a potential new boyfriend!)
I think I'm having a mid-life crisis 
I've had some wine tonight and I'm going to be working tomorrow so if I can take the shame, I will check back after that.
Thank you for reading (whatever the fuck this rambling was)
